How Browser and server works
Download as PPT, PDF1 like479 views
PHP is a server-side scripting language used for web development that allows dynamic content on websites. It runs on a web server and processes scripts embedded in HTML files before returning plain HTML to browsers. When a browser requests a PHP file, the PHP script is executed on the server and generates HTML which is then sent to the browser. XAMPP and WAMP are local development environments that allow testing PHP scripts without an external server by emulating the Apache web server, MySQL database, and PHP runtime environment on a local computer.

PHP: Hypertext preprocessor Server-side scripting language (has to be run on a server, not in your browser) Open source and free to download (this means that the code behind PHP is freely available - this often means PHP hosting is cheaper than other platforms, such as ASP) Particularly suitable for web development.

This is called server-side scripting or server scripting. • Client-side scripting is about "programming" the behavior of the browser. • Normally, when a browser requests an HTML file, the server returns the file. However, if the file contains PHP, the script is executed on the server before the file is returned to the browser as plain HTML.

- 15. Slide 15 of 38 About Xamp or Wamp • Xamp was originally designed as a development application, so that people could test their scripts, codes and websites on their own computers without the need of an external server using all the services needed. The application is very easy to install, just running the installer will allow you to select the services you want to run on your computer, and when to run them. Once the program is installed, you can use its Control Panel application to start, stop or manage the services with ease. It features a very useful graphic interface, but there are also powerful terminal commands you can use to manage all the services.
